Date Oct. 2, 1997A drilling tool includes a tool head having at least one chip groove and a tool shank. A slotted sleeve is placed on the tool shank and closely surrounds the chip groove. The edges adjacent the slot lie on solid material of the tool shank. The chip grooves and the sleeve form channels for carrying away the chips removed at the workpiece machining base. Owing to the slot, the sleeve can be gently spread apart and pushed onto the tool shank from the end having the enlarged tool head.
